to wav...then i tried to import to tmpge dvd author,it said illegal audio format ,wouldn't let me continue..so i used goldwave to rencode that wav file to wave again,then tried to use the tmpge sound player to convert to ac3 but the encode button wont light up,,i have read and read all morning and am goin nuts,i also tried besweet but couldn't get it to work either,,i have the right codecs and have used tmpeg dvd author for ac3 in the past,,,please help,,,also one more thing the audio file is 1 sec shorter than the movie file,,,,thanks guys

Extract the audio in virtualdub as .wav, full processing mode.
Load it into tmpgenc, ES Audio only, encode as mp2.
